Portfolio overview

Cool Planet Energy System, Inc. has been granted 38 US utility patents between 2015 and 2020, placing Cool Planet Energy System, Inc. at rank #8,359 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.1 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a US Corporation, Cool Planet Energy System, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Cool sits between Clarios Germany Gmbh & Co. KG (38 patents, rank #8,355) and Delta Tooling Co., Ltd. (38 patents, rank #8,363) - the closest US assignees by grant volume. The composite Innovation Score of 48.9/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 4 grants, compared with 34 in the 2015–2019 window, a -88% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Cool Planet Energy System, Inc.'s 24.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cool Planet Energy System, Inc. against peers pursuing similar technology classes.
